Problem med dubbelpostning.

Av någon anledning så körs min ena stored procedure (insertIMDBmovie) två gånger, medans den andra (insertUserMovie) endast körs en gång (vilket är rätt) någon som kan se problemet?

Sub MySQLDataGrid_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs)
        Dim intMovieID As Integer
        ' If multiple ButtonField column fields are used, use the
        ' CommandName property to determine which button was clicked.
        If e.CommandName = "Select" Then
            ' Convert the row index stored in the CommandArgument
            ' property to an Integer.
            Dim index As Integer = Convert.ToInt32(e.CommandArgument)

            ' Get the last name of the selected author from the appropriate
            ' cell in the GridView control.
            Dim selectedRow As GridViewRow = MySQLDataGrid.Rows(index)
            Dim titleCell As TableCell = selectedRow.Cells(1)
            Dim strTitle As String = titleCell.Text

            Dim yearCell As TableCell = selectedRow.Cells(2)
            Dim intYear As String = yearCell.Text

            Dim imdbCell As TableCell = selectedRow.Cells(3)
            Dim strImdbID As String = imdbCell.Text

            ' Define data objects
            Dim conn As SqlConnection
            Dim comm As SqlCommand
            ' Read the connection string from Web.config
            Dim connectionString As String = ConfigurationManager.ConnectionStrings("moviedatabase").ConnectionString
            ' Initialize connection
            conn = New SqlConnection(connectionString)
            ' Create command
            comm = New SqlCommand("insertIMDBMovie", conn)
            ' Specify we're calling a stored procedure
            comm.CommandType = System.Data.CommandType.StoredProcedure
            ' Add command parameters
            comm.Parameters.Add("@title", System.Data.SqlDbType.NVarChar, 150)

            comm.Parameters.Add("@imdbid", System.Data.SqlDbType.NVarChar, 50)
            comm.Parameters("@imdbid").Value = strImdbID
            Try
                ' Open the connection
                conn.Open()
                ' Execute the command
                comm.ExecuteNonQuery()
               intMovieID = comm.ExecuteScalar

            Catch
                ' Display error message
                dbErrorMessage.Text = "Error submitting the IMDBmovie request! Please Try again later, and/or change the entered data!"
            Finally
                
                conn.Close()
                Label1.Text = "You Added " & Title & "."

            End Try

Dim conn2 As SqlConnection
                Dim comm2 As SqlCommand
                ' Close the connection
                

                conn2 = New SqlConnection(connectionString)
                ' Create command
                comm2 = New SqlCommand("insertUserMovie", conn2)
                ' Specify we're calling a stored procedure
                comm2.CommandType = System.Data.CommandType.StoredProcedure
                ' Add command parameters
                comm2.Parameters.Add("@userID", System.Data.SqlDbType.Int)
                comm2.Parameters("@userID").Value = Session("userID")
                comm2.Parameters.Add("@MovieID", System.Data.SqlDbType.Int)
                comm2.Parameters("@MovieID").Value = intMovieID
                comm2.Parameters.Add("@format", System.Data.SqlDbType.Int)
                comm2.Parameters("@format").Value = movie_formats.SelectedItem.Value.ToString()
                Try
                    ' Open the connection
                    conn2.Open()
                    ' Execute the command
                    comm2.ExecuteNonQuery()
                Catch
                    ' Display error message
                    dbErrorMessage.Text = "Error submitting the usermovie request! Please Try again later, and/or change the entered data!"
                Finally
                    ' Close the connection
                    conn2.Close()
                End Try

        End If

    End Sub

Kan det ha o göra med scope_identity i min stored procedure?

ALTER PROCEDURE insertIMDBmovie
(
@title nvarchar(150),
@year int,
@imdbID nvarchar(50)
)
AS
INSERT INTO movies (title, year, imdbid)
VALUES (@title, @year, @imdbID); 

Select Scope_Identity()
